ALEXANDER GEZA FENY, OF GHARLOTTENBURG, GERMANY.

TUBE-POST.

TocZZ whom it may concern:

Be it known that I, ALEXANDER GZA FENY, editor, of 40 Uhlandstrasse,Charlottenburg, Berlin, Germany, a citizen of the Kingdom of Hungary,have invented a new and useful Tube-Post, of which the following is aspecification.

The invention refers to tube post installations that is installations bymeans of which postal packages, letters parcels etc. are transported intubes without anyone accompanying them. Up to now air tight tubes wereemployed for this purpose as the principle of the installation dependedpartly on an increased, partly on a reduced air pressure. Also for such.plants, for which motoricor electric energy was proposed as drivingmedium, a tube closed on all sides was a condition, as it was deemed-indispensable to have to remove the air in front ofthe carriage4 bysuction in order to reduce the resistance Specification of LettersPatent.

Application filed October 7,

lt has however been ascertained that it is entirely'superfluous toconsider the air pres* sure on electrically driven carriages even iftraveling at a very high speed, if'care is taken that the interior ofthe tube communicates With the open air so that there is the ordinaryatmospheric pressure inside the tube. This can be explained by the factthat by the motion of the carriagesparticularly if they are traveling indifferent directions, air currents are created, in the direction of thetravel which can only be favorable to the working of the plant. It isalso possible that when the tube is in a suitable dimension to thecarriage the air in front and at the sides of the carriage will findsufficient room to escape so that no increase of the air pressure,opposing the advance of the carriage, will occur. ln order to facilitatethis escaping of the air and to assist the forming of the currents ofair and to regulate them, the tubes can be provided with swells oreXtensions at given distances from each other.

The arrangement according to the present invention affords the advantagethat-be sides a reduction in cost of the installation owing to the tightj ointing not being required side of the tube can be made accessibleany- `where land even while the tube isinuse, Withl Patented June 23,1908. 1905.

out any provision being required to shut 0H or preserve the insidepressure from the open Therefore it is ossible to place the carriage'tobe conveyedp into the tube also while the latter is otherwise in use,the walls of the tube can be opened during work for doing re airs orcontrolling the working, and the tubes can be made of materialspermeable to gases. Besides the above arrangement oifers the furtheradvantage that the air pressures caused by the movement of the carriagesare made eifectless by the communication with the open air, so that evenat high speed an increase of the air pressure will not occur. Thisarrangement allows of economically 'erecting tube post installationsalso for long distances, no limit being made as to length and size ofthe tubes, so that tubes of more than 1 m. diameter are possible tolengths reckoning by miles. lt is only necessary that the electriccurrent used for driving the carriages is of suflicient strength,thespeed being able to be increased far beyond that allowable for theconveyance of persons, so

much the more as the wallsof the tube aiford a safe guard againstderailments and the carriages have not to overcome any lateral pressureof wind.

The tubes can be arranged both above as below the ground level. ln thelatter instance the communication with the open air is suitably made bychannels leading to the surface of the earth. These channels can at thesame time serve to take instruments for controlling the working of theinstallation and can be made of such size that they will likewise giveaccess to the tubes for doing repairs, placing the carriages to beconveyed yand the like. The tube can for this purpose also be providedwith swells at given distances for allowing a more easy compensation ofthe air pressure inside the tube.

The invention may of course be put into 'practice in various ways.

A mode of carrying it out is exemplified in the accompanying drawings.

Figure l is a section through part of a pipe conduit with a carriageintended for the conveyance of postal packages. Fig. 2 is a crosssection through the pipe, showing that a double track is used forworking the system.

Fig. Sis a section' along A-A in Fig. 2. Fig.

The pipe conduit 3 is placed in the ground 1 at a suitable depth fromthe level 2, the pipe consisting of any suitable material. The pipes maybe made of iron, clay, but suitably of reinforced concrete. The diameterof the pipes is suitably chosen of up toV 1n the pipe 3 the rails 4, 4are pro- 1 meter. vided yat the upper part, the rails 5, 5 at the lowerpart. Between two each rails 4 and 5 run the carriages 6 conveying ythepostal` packages, these carriages running with rolls, 77 & 8, 8 on saidrails. be made of any shape whatever and also of any material. It willbe found 4advisable to give them a shape pointed at the front iny orderto reduce the resistance of the air. Their rear end is suitably providedwith a buffer arrangement so as to reduce the shock as far as possibleshould a carriage run against the one in front. 1n the type shown thisbuffer arrangement consists of plate 10, which has a recess 11 of theshape of the point of a carriage 9. This platelOglides with arms 12 inslots 13. The plate 10 is further under action of a spring-,14, vwhichis attached to a projection 15 of 4the back of the car 16. The drivingmotor 17 is Jfitted into the carriage, and receives the current throughthe rail 4 and the rolls 7. The rotation of the motor is transmitted bygearing 18 on to the roll 7. The rail 5 serves for conducting back thereturn current. v

ln the installation shown forexempliiication it has been taken asgranted that either at the termini of the line -or at intermediateTstations there are sources of electricity, from which the currentA canbe fed into the conductors 4.

These air canals can then at thesame time be Varranged to'take means of control for the conductors ofthe current as illustrated in the installation shown in thelaccompanying drawings. From the conductor 4 a wire conduit 2O isbranched off, from conductor 5 a wire conduit 21. The

respective poles of these branchings 22 & 23 respectively, are carriedup so far towards the surface of the earth 2 that they are' easilyaccessible from outside, so that by attaching a suitable instrument, theconductors of the current can be easily controlled.

A special advantage of the present invention is that the pipe conduits 3in which the carriages run, can also be used for other purposes as well,as exemplified by the system shown.v The space inside the pipes isseparated by a partition 24. In the one, the larger space run thecarriages carrying the postal packages in the other space 25 cables,insulated wires etc. 26 are arranged. The space can also be used forwater conduits or the like, or for laying gas pipes and the like. Thewires or wire conductors respectively can serve for any purposewhatever. They can'serve for telephones, telegraphs or the like. Herebythe considerable advantage will be -obtained that special canals orconduits for such conductors need not be separately built. Also theconductors carrying the current for drivin@ the carriages can lbesidesherefor, be used for telephones, telegraphs or the like.

4The carriages conveying the postal pack`- ages canof course as wellbemade after the suspended railway type instead of the type shown, arailway runnin on tracks.
